We now have Bono East and Ahafo regions. These new regions have been carved from the existing “Brong-Ahafo Region.” I think this is the time to change the names of some of our regions and towns, which do not make sense or have any meaning.

Brains do a lot of work while we sleep—far from being a passive behavior, sleep is actually critical to brain health, and as a result, mental and cognitive health.

Our brain is not designed to create happiness, as much as we wish it were so. Our brain evolved to promote survival. It saves the happy chemicals (dopamine, serotonin and oxytocin) for opportunities to meet a survival need, and only releases them in short spurts which are quickly metabolized. This motivates us to keep taking steps that stimulate our happy chemicals.
Slavery was practiced throughout the American colonies in the 17th and 18th centuries, and African slaves helped build the new nation into an economic powerhouse through the production of lucrative crops such as tobacco and cotton. By the mid-19th century, America’s westward expansion and the abolition movement provoked a great debate over slavery that would tear the nation apart in the bloody Civil War. Though the Union victory freed the nation’s four million slaves, the legacy of slavery continued to influence American history, from the Reconstruction era to the civil rights movement that emerged a century after emancipation.
